Airborne LiDAR Survey

Pioneer in Airborne LiDAR Systems

GDS first introduced the MATRIX system in Malaysia in 1989.

Now in its 6th generation, the MATRIX LiDAR system has been used in over 130 projects worldwide.

The MATRIX system can be either Helicopter or Fixed Wing Aircraft mounted, with hot-swappable systems comprising:

GDS has five RIEGL digital waveform scanners, which possess infrared laser pulse repetition rates that go up to 400 kHz. These scanners allow the system to acquire a continuous pulse return that, when analysed, produces an optimum density of points.

The IMU measures the orientation of the sensors, in roll, pitch and heading/yaw. These values are used in the calculations together with the DGPS positional information and the laser altimetry data to produce the XYZ values of the points.

GDS has 4 types of High Resolution Cameras to capture the ground data. Each frame captured  contains the time,  coordinated with the GPS positioning and reference time stamps. This allows GDS to capture high quality data points with high accuracy.

GDS uses 2 types of high-definition video cameras to capture live footage of the area being captured

GDS uses a high performance GPS receiver with fast data update rates, mounted in the aircraft’s tail, away from obstructions which minimizes GPS signal interruptions,  resulting in better data accuracy.
